BUNG-SEAL.

Specification of letters l atenti Patented 22,

' Application filed April 15 1915. Serial No. 21,575.

To all whom it may concern.

Be it known that I, JOHN M. HOTHERSALL, a citizen of the United States,residing in Brooklyn, in the countyof Kings and State of New York, haveinvented a new and useful Improvement in Bung-Seals, of which thefollowing is a specification.

My invention relates in general to metal seals and more particularly toseals of this character adapted to be secured over the bung of a barrelto prevent its removal without leaving visible evidence thereof.

A principal object of this invention is the provision of a seal of thecharacter described, which will prevent its removal when once positionedwithout the breaking of the seal.

A further object of the invention is the provision of such a device soconstructed that no fiat tool can be inserted thereunder in such mannerthat the tool may be engaged beneath the material on both sides of theweakening score lines provided.

A further object of the invention is the provision of a bung seal whichmay be positioned with little danger of breaking it.

Other objects and advantages of the invention will be apparent as it isbetter understood from the following description when considered inconnection with the accompanying drawing illustrating a preferredembodiment thereof.

On the drawing,

Figure 1 is a side elevation of a barrel provided with a seal embodyingmy invention;

Fig. 2 is a section taken substantially on the line 22 thereof;

Fig. 8 is a large top plan embodying my invention;

Fig. 4 is a perspective of the seal in in verted position; and

Fig. 5 is a section on the line 55 of Fig. 3.

For the purpose of illustrating my invention I have shown it embodied ina hung seal generally designated at A and secured over a bungB of abarrel C. The seal in the present instance consists of a 'metal disk ofgeneral circular form. This disk is provided with a plurality ofrectangularly spaced recesses 6 extending in from the circular edge;These recesses are relatively narrow. Between each pair of adjacentreview of a. seal ter of said member.

cesses the edge of the disk is bent downwardly and is corrugated, asbest seen in Figs. 4 and 5. This edge, designated at 7,

recesses 6 is not great, so that an inwardly extending substantiallycontinuous, though broken flange is formed about the edge of the seal.When, therefore, it is desired to drive the seal in place over the bung,little danger of breaking the seal from the blows of a mallet or otherhammer having a head sufiiciently broad enough to cover the seal, ispresent. The seal may even be positioned with a small headed hammer ifordinary care be employed; When in final position, as shown in Fig. 2,the narrow recesses 6 prevent the entrance of any tool which could pressupon both sides of both score lines of the recess in which the tool isinserted. In other words, the arrangement provides a seal which not onlycannot be drawn away without damage to the seal, but which also cannotbe worked loose through the use of ordinary tools or equipment- It willbe manifest that the invention and many of its attendant advantages willbe understood from the foregoing description, and it will be apparentthat various changes may be made in the form, construction. andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing any ofits material advantages, the form'hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A bung seal comprising a metal memher having its edge recessed atintervals and formed between said intervals with edges to be driven intothe material of the barrel.

said member being weakened along lines ]O1I11I1g said recesses, saidlines extendlng behind said edges and forming with said recesses acontinuous weakening about the cen- 2. A sheet metal bung sealconsisting of extending from one recess to theneXt, be-
